When the lens is focused to infinity, the distance from that optical center inside the lens to the camera’s image plane (i.e. the sensor, film, or plate, sometimes indicated by a Φ symbol on modern cameras) is referred to as the lens’s focal length. To put it simply:focal length...
Focal length, as discussed above, is the distance between the lens and the image sensor. It’s that property of a camera lens that determines how wide or narrow the angle of view is. Focal distance is a different concept. It refers to the distance between the subject of your image and ...

Term: Focal Length Description: Focal length is a number expressed in millimeters (mm) that indicates a lens’s field (angle) of view. A The number itself refers to the measured distance between the point where light converges (the nodal point) and the image plane (sensor) when a subject...
Camera calibration file—Includes measurements of sensor characteristics, such as focal length, size and shape of the imaging plane, pixel size, and lens distortion parameters. In photogrammetry, the measurement of these parameters is called interior orientation (IO), and they are encapsulated in a ...
If a camera’s shutter is inside the camera, then it is a focal plane shutter. A focal plane shutter is actually two separate shutters, both of which are spring-loaded to travel in the direction to create the actual exposure itself. One of the shutters performs the “opening” of the sh...
Pinhole Camera Model A pinhole camera is a simple camera without a lens and with a single small aperture. Light rays pass through the aperture and project an inverted image on the opposite side of the camera. Think of the virtual image plane as being in front of the camera and containing ...
